摘要:
A dielectric ceramic composition includes a compound having perovskite type crystal structure shown by a general formula ABO3, where A is at least one selected from Ba, Ca and Sr, and B is at least one selected from Ti and Zr, as a main component. The dielectric ceramic composition includes, as subcomponents, with respect to 100 moles of the compound, 1.0 to 2.5 moles of an oxide of RA (Dy, Gd and Tb); 0.2 to 1.0 mole of an oxide of RB (Ho and Y); 0.1 to 1.0 mole of an oxide of RC (Yb and Lu); 0.8 to 2.0 moles of Mg oxide and 1.2 to 3.0 moles of an oxide including Si in terms of RA2O3, RB2O3, RC2O3, Mg and Si, respectively. Also, when contents of the oxide of RA, RB and RC with respect to 100 moles of the compound are defined as “α”, “β” and “γ”, respectively, the “α”, “β” and “γ” satisfy relations of 2.5≦(α/β)≦5.0 and 1.0≦(β/γ)≦10.0. According to the present invention, a dielectric ceramic composition having good properties can be provided.

摘要:
In some examples, a method for performing maintenance-cost-aware billing is described. The method may include generating a version of a virtual machine image. The method may also include calculating a usage charge for usage of an instantiated virtual machine corresponding to the version of the virtual machine image. The calculation of the usage charge may be based on an age of the version of the virtual machine image.
摘要:
An information processing apparatus stores a first threshold of a common carrier, the common carrier charging according to the first threshold to be applied to a packet communication volume in each first unit period; performs a packet communication to and from a communication apparatus of the common carrier; calculates a packet communication volume in each second unit period shorter than the first unit period; and controls the packet communication based on the packet communication volume in the second unit period so as to keep the packet communication volume in the first unit period below the first threshold.
摘要:
The information service providing device of the disclosure of the present application selects sensors which may be used for the implementation of an information service to be provided within a plurality of sensors which the device can make use of, and in addition, selects the most appropriate one within the sensors which may be used and selects an appropriate parameter for the sensors and processing programs in order for the information service to be provided appropriately, and set to these in response to the environment in which the information service is implemented. Furthermore, the information service providing device of the disclosure of the present application provides, with only the receipt of the designation of desired information service by a user, various information services are provided by appropriately combining various kinds of sensors and a plurality of processing programs.
